Detailed Description
in order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
as shown in fig. 1, a system for performing service transmission according to an embodiment of the present invention includes: a terminal 10 and a network side device 20.
the terminal 10 is configured to determine a receiving mode corresponding to a multicast service to be received according to the multicast parameter information; and receiving the multicast service to be received, which is sent by the network side equipment, according to the determined receiving mode.
And the network side device 20 is configured to send the multicast service to be received to the terminal.
The terminal determines the receiving mode corresponding to the multicast service needing to be received according to the multicast parameter information, and receives the multicast service needing to be received, which is sent by the network side equipment, according to the determined receiving mode. The terminal determines the receiving mode corresponding to the multicast service to be received according to the multicast parameter information, so that the terminal can receive the service to be received in the scene covering the enhanced area; further improving system performance.
The multicast service that the terminal needs to receive in the embodiment of the present invention is a multicast service that the terminal is interested in, such as a multicast service subscribed by a user.
in implementation, the terminal needs to acquire the multicast parameter information before determining a receiving mode corresponding to the multicast service to be received according to the multicast parameter information.
There are many ways for the terminal to obtain the multicast parameter information, for example, the multicast parameter information may be set in a protocol, so that the terminal may determine the multicast parameter information that is set in advance.
One alternative is to: and the network side informs the terminal of the multicast parameter information.
Specifically, the network side device determines at least one piece of multicast parameter information and sends the at least one piece of multicast parameter information to the terminal;
Correspondingly, the terminal receives the multicast parameter information from the network side equipment.
the network side device may send the multicast parameter information to the terminal in a multicast mode, a broadcast mode, or the like.
optionally, the network side device determines at least one piece of multicast parameter information for each multicast service, that is, one multicast service corresponds to at least one piece of multicast parameter information, and the multicast parameter information corresponding to different multicast services may be the same or different; and/or
the network side equipment determines at least one piece of multicast parameter information for the cell managed by the network side equipment, namely, the multicast services in the cell mostly correspond to the same multicast parameter information, and the multicast parameter information corresponding to different multicast services is the same.
Optionally, when the terminal determines a receiving mode corresponding to a multicast service to be received according to the multicast parameter information, it needs to determine whether a current terminal state matches with the multicast parameter information;
If yes, determining that the receiving mode is a multicast mode; otherwise, determining the receiving mode to be a unicast mode.
The multicast parameter information includes, but is not limited to, some or all of the following information:
Retransmission times of the service;
The signal strength range of the terminal;
the moving state of the terminal.
Wherein, the terminal state includes but is not limited to part or all of the following:
The signal strength of the terminal;
The mobile state of the terminal;
a coverage enhancement level of the terminal.
in implementation, the specific meaning of the current terminal state is different according to the information included in the multicast parameter information.
for example, if the multicast parameter information includes the signal intensity range of the terminal, the current terminal state is the current signal intensity of the terminal; for example, the multicast parameter information includes a mobile state of the terminal, and the current terminal state is the current mobile state of the terminal; if the multicast parameter information further includes the coverage enhancement level range of the terminal, the current terminal status is the current coverage enhancement level.
the Signal strength of the terminal may be determined according to parameters such as Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ) of the terminal. If the current signal intensity of the terminal is in the signal intensity range of the terminal included in the multicast parameter information, the terminal confirms that the signal intensity is matched with the multicast parameter information; on the contrary, if the current signal strength of the terminal is out of the signal strength range of the terminal included in the multicast parameter information, the terminal confirms that the signal strength is not matched with the multicast parameter information.
the moving state of the terminal can be determined by comparing the current speed of the terminal with a threshold value. For example, 0-40 km/h can be defined as a low speed state; setting 40-100 km/h as a medium-speed state; the high speed state is defined as 100km/h or more.
the mobile state of the terminal may also be determined by following the mobile state of the UE in the connected state and the idle state in the existing network, which is not described herein again.
It should be noted that the above numerical values are only examples, and specific numerical values may be set according to specific situations, requirements, and the like.
if the multicast parameter information comprises that the mobile state of the terminal is low speed, the terminal confirms that the multicast parameter information is matched with the current mobile state of the terminal; otherwise, if the current moving state of the terminal is not the low speed, the terminal confirms that the multicast parameter information is not matched.
optionally, if the terminal determines that the receiving mode for receiving the multicast service to be received is the multicast mode, the terminal receives the multicast service to be received, which is sent by the network side device, according to the matched multicast parameter information.
for the network side device, the corresponding multicast service needs to be sent according to the multicast parameter information service.
If one multicast service corresponds to a plurality of multicast parameter information, the network side equipment needs to send the corresponding multicast service according to each multicast parameter information service.
For example, the multicast parameter information 1 includes:
{ TMGI1, repetition 2, RSRP Range 1 };
The multicast parameter information 2 includes:
{ TMGI1, repetition: 512, RSRP Range 2 }.
Wherein, TMGI (Temporary Mobile Group Identity) is used to indicate the multicast service corresponding to the multicast parameter information;
the retransmission is used for representing the number of times of repeated transmission of the multicast service;
The RSRP range represents the range of signal strengths of terminals allowed to receive via multicast.
the network side device needs to send the multicast service of the TMGI1 according to the multicast parameter information 1, and needs to send the multicast service of the TMGI1 according to the multicast parameter information 2.
optionally, if the terminal determines that the receiving mode for receiving the multicast service to be received is a unicast mode, the terminal needs to notify the network side device to send the multicast service in the unicast mode.
Specifically, the terminal sends unicast information to the network side device, so that the network side device sends the multicast service to be received to the terminal in a unicast manner.
Correspondingly, if receiving the unicast information from the terminal, the network side device sends the multicast service to be received to the terminal in a unicast mode.
there are many ways for a terminal to send unicast information to a network side device, for example, unicast information may be sent through an application layer message; the unicast information may also be transmitted through a RRC (Radio Resource Control) message.
The embodiment of the present invention is applicable to any mode as long as unicast information can be transmitted to the network side device.
the unicast information includes, but is not limited to, part or all of the following information:
a service identifier which is required to be received by the terminal;
indication information for notifying unicast.
if the unicast information includes the service identifier that the terminal needs to receive, the unicast information including the service identifier that the terminal needs to receive may be preempted to indicate that the terminal needs to receive the multicast service in the unicast mode, i.e., the network side device knows that the terminal needs to send the multicast service in the unicast mode when receiving the unicast information including the service identifier that the terminal needs to receive.
if the unicast information comprises indication information for notifying unicast, if the network side equipment only has one multicast service currently, the multicast service can be directly sent in a unicast mode; if the network side equipment has a plurality of multicast services currently, the terminal can be informed to report the multicast services needing to be received, the multicast services needing to be received by the terminal are determined according to the received feedback information, and the multicast services needing to be received are sent to the terminal in a unicast mode.
The network side device in the embodiment of the present invention may be a base station (such as a macro base station, a home base station, etc.), or may be another network side device.

The following describes the embodiments of the present invention by way of examples.
Embodiment 1, one multicast service corresponds to a plurality of multicast parameter information.
in this embodiment, one multicast service corresponds to a plurality of multicast parameter information to satisfy the repetition requirements under different coverage enhancement areas. For example, if an area in a certain cell is in deep coverage, and the required number of repetitions is 512, and the remaining coverage does not need to be repeated or is repeated a little, the network side device may send the TMGI of the multicast service a in two times: once dedicated to deep coverage areas and once for other covered areas.
step 1: the network side equipment sends two pieces of multicast parameter information.
the multicast parameter information 1 includes:
{ TMGI1, repetition 2, RSRP Range 1 };
the multicast parameter information 2 includes:
{ TMGI1, repetition: 512, RSRP Range 2 }.
The TMGI is used for representing the multicast service corresponding to the multicast parameter information;
The retransmission is used for representing the number of times of repeated transmission of the multicast service;
The RSRP range represents the range of signal strengths of terminals allowed to receive via multicast.
the network side device may send the multicast parameter information in various manners, such as a broadcast manner, a multicast manner, and the like, which is not limited herein. Meanwhile, other information corresponding to the multicast service in the prior art also needs to be sent.
it should be noted that the embodiment of the present invention is applicable as long as multicast parameter information can be transmitted to a terminal.
step 2: assume that the UE1 is interested in TMGI1 and determines that the location is a deep coverage area based on the current RSRP value.
if the current RSRP value of the UE1 is in the range of 2, the UE determines that the current RSRP value is matched with the multicast parameter information 2, and receives the multicast service needing to be received through the multicast parameter information 2 in a multicast mode;
If the current RSRP value of the UE1 is in the RSRP value range 1, the UE determines that the current RSRP value is matched with the multicast parameter information 1, and receives the multicast service to be received in a multicast mode according to the multicast parameter information 1.
Example 2: the network side equipment respectively sends one piece of multicast parameter information for each multicast service, and the UE which is not in the deep coverage area required by the multicast parameter information triggers a unicast mode.
In this manner, the network side device sends one piece of multicast parameter information for each multicast service, for example, the network side device is to send the multicast services of TMGI1 and TMGI 2. Most UE of the network side equipment is in a coverage area which does not need to repeat or send a small amount of UE repeatedly, a small amount of UE is in a deep coverage area, and the required repetition number is 1024. Statistics shows that the UEs requiring reception by the TMGI1 service and the TMGI2 are mostly in a coverage area that does not need to be repeated or needs to be sent repeatedly only by a small amount, so that reception by the UEs is only required to be satisfied during multicast without repeated sending for many times, thereby reducing air interface overhead. And if the UE in the deep coverage area is interested in the multicast service, triggering a unicast mode to obtain the multicast service.
step 1: the network side equipment sends two pieces of multicast parameter information.
the multicast parameter information 1 includes:
{ TMGI1, repetition 2, corresponding RSRP range 1 };
the multicast parameter information 2 includes:
{ TMGI2, repetition 4, corresponding to RSRP range 2 }.
the TMGI is used for representing the multicast service corresponding to the multicast parameter information;
the retransmission is used for representing the number of times of repeated transmission of the multicast service;
the RSRP range represents the range of signal strengths of terminals allowed to receive via multicast.
The network side device may send the multicast parameter information in various manners, such as a broadcast manner, a multicast manner, and the like, which is not limited herein. Meanwhile, other information corresponding to the multicast service in the prior art also needs to be sent.
It should be noted that the embodiment of the present invention is applicable as long as multicast parameter information can be transmitted to a terminal.
Step 2: assuming that the UE1 is interested in the TMGI1, but the UE1 is currently in a deep coverage area, and finds that the RSRP range corresponding to the TMGI1 is not satisfied according to the current RSRP value, the UE1 triggers, through inter-layer interaction, establishment of unicast connection between the application layer and the network side device, and obtains a multicast service to be received through a unicast manner.
For example, the UE1 may send unicast information to the network side device through the application layer;
Correspondingly, after receiving the unicast information from the UE1, the network side device knows that the UE1 needs to obtain the multicast service to be received in a unicast manner, establishes a unicast connection with the UE1, and sends the multicast service to be received to the terminal in a unicast manner.
Example 3: the network side equipment only sends one piece of multicast parameter information, all multicast services share the multicast parameter information, and the UE which is not in the deep coverage area required by the multicast parameter information triggers a unicast mode.
In this embodiment, the network side device sends one piece of multicast parameter information for all multicast services.
Such as network side devices that need to send the multicast services TMGI1 and TMGI 2. Under the coverage of a network side, a plurality of coverage enhancement areas exist, and most of coverage enhancement areas can ensure the UE to receive the coverage enhancement areas by repeatedly sending the coverage enhancement areas for 32 times; there is a small range, in the deep coverage area, the number of times of repeated transmission is 1024, and the distributed UEs are sparse. At this time, the network side device may only ensure multicast reception in most coverage enhancement areas, and for a deep coverage area, if the UE has a demand, the UE transmits the multicast in a unicast manner according to the demand.
step 1: the network side equipment sends a multicast parameter message.
the multicast parameter information 1 includes:
{ repeptition 32, corresponding RSRP range 1 }.
Wherein, the retransmission is used for representing the number of times of the repeated transmission of the multicast service;
The RSRP range represents the range of signal strengths of terminals allowed to receive via multicast.
The network side device may send the multicast parameter information in various manners, such as a broadcast manner, a multicast manner, and the like, which is not limited herein. Meanwhile, other information corresponding to the multicast service in the prior art also needs to be sent.
It should be noted that the embodiment of the present invention is applicable as long as multicast parameter information can be transmitted to a terminal.
Meanwhile, other information corresponding to the multicast service in the prior art also needs to be sent.
for example, in an SC-PTM (Single Cell Point To multipoint) mode, TMGI, G-RNTI (Group-Radio Network Temporary Identifier) information, etc. may be sent through an SC-CCCHSC-MCCH (Single Cell Multicast Control Channel, Single Cell Multicast common Control Channel) Channel.
Step 2: assuming that the UE1 is interested in the TMGI1, but the UE1 is currently in the deep coverage area, and finds that the RSRP range corresponding to the TMGI1 is not satisfied according to the current RSRP value, the UE1 obtains the service identifier to be received through inter-layer interaction, and triggers the AS layer to send a request through an RRC message, where the request includes the service identifier to be received and/or an indication of desired unicast transmission.
Correspondingly, after receiving the unicast information from the UE1, the network side device knows that the UE1 needs to obtain the multicast service to be received in a unicast manner, establishes a unicast connection with the UE1, and sends the multicast service to be received to the terminal in a unicast manner.
example 4: the network side equipment only sends one piece of multicast parameter information, all multicast services share the multicast parameter information, and the UE which is not in the speed range required by the multicast parameter information triggers a unicast mode.
in this embodiment, the network side device sends one piece of multicast parameter information for all multicast services.
for example, the network side device needs to send the multicast services TMGI1 and TMGI2, and under the coverage of the network side, there are multiple coverage enhancement areas, and most of them can meet the receiving requirements of UEs under all the coverage by repeatedly sending 256 times. Due to the repeated transmission, the time for receiving the multicast service becomes long. If the UE receives the service in a multicast mode and the moving speed is too high, frequent cell replacement is needed to maintain the service continuity type, and at the moment, the multicast service to be received can be received completely as soon as possible in a unicast mode.
Step 1: the network side equipment sends a multicast parameter message.
The multicast parameter information 1 includes:
{ repeptition is 256, the corresponding maximum moving state is low };
Wherein, the retransmission is used for representing the number of times of the repeated transmission of the multicast service;
the maximum moving state indicates a moving speed of the terminal that allows reception through multicast.
The moving speed of the terminal may be divided into a plurality of states, such as a high speed, a medium speed, and a low speed, according to the set threshold. The specific threshold size may be set by the protocol; the terminal may also be notified by the network side.
The mobile state of the terminal may also be determined by following the mobile state of the UE in the connected state and the idle state in the existing network, and the specific manner is similar to the above, which is not described herein again.
step 2: assuming that the UE1 is interested in the TMGI1, but the UE1 is currently in a medium-mobility state and does not satisfy the mobility range in the multicast parameter information sent by the network side device, the UE1 decides to obtain the TMGI1 service to be received in a unicast manner.
At this time, the UE1 may obtain the TMGI1 service by triggering and establishing a unicast mode through the application layer in a manner similar to that in embodiment 2; the TMGI1 service can also be obtained by triggering establishment of unicast through RRC message in a manner similar to that of embodiment 3.
the mobility state range of the UE initiating unicast may also be predefined, for example, the multicast parameter information sent by the network side device may include a transmission repetition number excluding a speed range, and the predefined low-speed UE may receive the multicast parameter information in a multicast manner.
accordingly, the non-low speed UE can be directly obtained through the unicast mode.
